Added -pullup support to set_io constraint #69

Closed set-soft closed 6 years ago

set-soft commented 7 years ago

This allows users to dis/enable pull-ups using constraints using the -pullup option. This option is supported by the SBT tool-chain. This patch should also fix some bugs in the set_io options parser (take a look at the [1] vs [i] changes) It also adds a function called void note(const std::string &msg) used to report information. The code uses it to inform the user that a pull-up constraint was applied.
